We might like to think of ourselves as autonomous beings who get to decide who we are going to be, but we are likely much more malleable than we think. We are often defined by the structure that keeps us captive. In some ways our desires are so socially constructed that they can't rightfully be called our own.

'Tragedy admires man. Comedy feels a bit sorry for him.' We think we are kings or queens, masters of the universe or at least our own destiny. We forget that a foot may crush us, or that the wind may knock us down. We are not in control. We are subject to gas and sloughing skin and dirty pores. Most of our joints will eventually fail us. We have big brains which we can imagine great things, but we can't really get off the ground. It's like we have wings but we can't fly.
